Can an Atheist be a White Nationalist? As well would an atheist white nationalist be accepted by Christian white nationalists?

Yes, there are atheist and agnostic White Nationalists.

I tend to identify more as an agnostic myself, not an atheist. When it comes to topics relating to the supernatural, I just say "I don't know" and leave it at that. But I'm not going to make a point about it or argue over it.

If someone wants to put a nativity scene in a public park, I see it as no big deal, and it could be just as easily viewed as a cultural display. Atheists get way too overzealous and political about those things, and sometimes they go overboard. They're also too heavily associated with Marxists and other leftist groups, which is why I tend to not identify as "atheist."

I see "atheism" as more of a political position, whereas "agnosticism" is more philosophical and scientific, in my opinion.

Yes. I really don't see why Atheist white Nationalists wouldn't be accepted by Christian white Nationalists... Or maybe you're just the kind of person that was brainwashed into thinking we're all Christians.

I'm an atheist. I tend to percieve agnostics as taking the "I don't know if there's a God" approach while atheists take the "I'm pretty sure there's not a God" approach. "Atheist" just feels like the more correct term for my opinion, although I had a very religious upbringing, and have also been more anti-Christian in the past than today. I have to admit that I have been religiously and politically all over the map in my lifetime, equally certain I was correct each time. Then I read something new and change my mind. I have no answers for how it all started (scientists probably do, but I haven't read all the books). These days, I tend to defend Christians a lot because I feel like the media bullies them a lot. I think everyone has the right to believe what they want. That was our forefathers' ideal for this country and, frankly, they made that decision at a time when almost everyone was some type of Christian. Freedom is what this country stood for, and I can't think of a better ideal for a country to have in order to promote human happiness. I also love everything that's even remotely related to Christmas.
